Founding Product Marketing Manager (PMM)

SellScale • San Francisco, CA

1d • Onsite

About The Position

As businesses grow larger, their sales spend grows disproportionately because sales, especially outbound, is still human-driven: it's subjective, hard to measure, and doesn't scale like code. Lix has built a proprietary memory system that allows us to take the place of an entire digital team—starting with sales (Selix.AI). We call it the Language Interface Experience (LIX), and it's already transforming how entire departments operate. As our Product Marketing Manager, you're going to help spread the gospel about LIX and how it's transforming entire departments. Practically, that means you own all brand/content/inbound activities. You're a swiss army knife generalist—videos, email lists, billboard campaigns, outbound strategy, and everything in between. If it needs to go from 0→1, you're the one taking it there. Think "scrappy startup PMM" — not "big company content marketer."

Requirements

• Willing and able to work 5 days a week in-person at our SF office, minimum
• Prior experience in product marketing, content creation, and video editing in a fast-paced startup environment
• Comfortable with long hours, steep learning curves, and wearing multiple hats
• Strong interest in agentic AI, outbound sales, or startup operations

Nice To Haves

• Familiarity with tools like Notion, Excalidraw, Zapier, HubSpot, and the broader marketing stack is a plus

Responsibilities

• Produce and edit video content that tells our story
• Build and manage our email list and nurture campaigns
• Plan and execute billboard campaigns
• Take marketing initiatives from 0→1 by yourself
• Ensure we are consistently running outbound and driving pipeline
• Write landing pages, set up HubSpot flows, cut videos, AND think strategically about positioning—not just write briefs for agencies
• Manage multiple vendors we work with for video production and content
• Coordinate stakeholders for design work
• Own and manage the systems powering our inbound engine (content marketing, automation, attribution)
